C# winfrom 菜单加图标

C# winfrom 菜单加图标

用这个控件 ToolStrip，然后再添加一个toolStripButton控件，属性DisplayStlye = Image，然后设置按钮图片就可以了

双击form_closing事件，然后直接写以下代码，使得窗体无法关闭：

private void form_formclosing(object sender, formclosingeventargs e)     {     e.cancel = true;     }

c#中可没有直接屏蔽关闭按钮的方法，你硬要这样也可以：

[system.runtime.interopservices.dllimport("user32.dll")] static extern intptr getsystemmenu(intptr hwnd, bool brevert); [system.runtime.interopservices.dllimport("user32.dll")] static extern int getmenuitemcount(intptr hmenu); [system.runtime.interopservices.dllimport("user32.dll")] static extern bool drawmenubar(intptr hwnd); [system.runtime.interopservices.dllimport("user32.dll")] static extern bool removemenu(intptr hmenu, uint uposition, uint uflags); protected override void onload(eventargs e) {     base.onload (e);     const int32 mf_byposition = 0x400;     const int32 mf_remove = 0x1000;     intptr menu = getsystemmenu(this.handle, false);     int menucount = getmenuitemcount(menu);     if (menucount > 1)     {     //删除菜单的「关闭」和分隔符     removemenu(menu, (uint) (menucount - 1), mf_byposition | mf_remove);     removemenu(menu, (uint) (menucount - 2), mf_byposition | mf_remove);     drawmenubar(this.handle);     }
